I have always been the same size for years, because I always watched what I ate. I am not a big eater, but I have put on several pounds. I have even cut down but I still seem to put on the weight. I am over 50 and I am wondering why am I gaining all this weight. (It is very depressing.) What can I do to get it off?

Gotta remember as we age, our metabolic rates also slow down which contributes to weight gain. Although, a wide range of factors come into play such as; Genetics, gender, age, diet and lifestyle are all factors of weight gain. Do you exercise regularly?

u are only 50, but believe me i am 74, i am only 5'10 but i am 74 kg. isnt that so big..?? i think my bones are heavy.

with the age the metabolism rate of the organisms change and this may cause the difference and weight gain that you are experiencing.
50 kilograms is not that much, actually is not much at all, what is your sex and what is your age?
